Default Transducer won't read depth on speed

Hello THT. I have been experiences on my new Garmin Combo with a Transducer on my aluminum boat. When ever I get on cruising speed, the transducer won't pick up the depth. It keeps blinking a certain number. Any tips or anyone have any similar experiences? and yes the transducer is level to my boat. Thanks!

There's a couple things... First, your transducer could be in a spot where it's not in clean water while running. If it's behind a strake or even a raw water intake there could be just enough bubbles to prevent it from reading. Second, if your unit has CHIRP, I found that when running I use the split CHIRP/Traditional mode and traditional always reads even when CHIRP doesn't. Third, you may need to move your transducer down on the transom a little.

CHIRP mode doesn't do as well in reading the bottom while at planing speeds as a single high frequency such as 200 kHz. if your hull has rivets, they can be causing turbulent water flow that will degrade sonar performance.

Typical Garmin problem.
If your transducer is in "clean water", no obstructions in front. Lower the transducer by 1/2 inch.
Even the Chirp units will read if you do.
